It should be noted that similar numbers and letters indicate similar items in the following drawings, therefore once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
Referring to FIGS. 1 to 6 , the novel plant growth accelerator 100 of the present disclosure includes a negative voltage device 1. The negative voltage device 1 includes a power supply assembly and a negative voltage generator 3. The power supply assembly includes a power supply 2, which is electrically connected to the negative voltage generator 3. The output terminal of the negative voltage generator 3 is electrically connected to a negative electrode 4. The negative electrode 4 can be directly or indirectly connected to the plant, either hung on the plant, inserted into the plant, or placed into the soil to provide negative electricity to the plant. The power supply assembly supplies energy to the power supply 2, enabling it to power the negative voltage generator 3.
The negative voltage generator 3 is a low-frequency negative voltage generator, with the specific model being ZH20. It promotes plant growth while minimizing adverse effects on the plant. The negative voltage generator 3 generates a negative high-voltage microcurrent to stimulate plant growth. By configuring the negative voltage generator 3 to produce this microcurrent and connecting it to the plant via the negative electrode 4, the plant gains more internal electrons, facilitating electron migration and enhancing growth. This method also helps reduce pests. Additionally, the negative charge promotes the plant's absorption of potassium, nitrogen, phosphorus, and other nutrients, further accelerating growth. The device can be hung on the plant without burning its roots, ensuring simplicity, safety, and a positive user experience.
In specific implementations, the DC or AC input to the negative voltage generator 3 undergoes EMI processing and lightning protection circuits before passing through a pulse circuit for overvoltage and current limiting. After high-low voltage isolation and other circuits, it is stepped up to high-voltage AC, which is then rectified and filtered using specialized electronic materials to produce a pure DC negative high voltage, which is transmitted to the plant via the electrode tip. The negative electrode 4 can be inserted into the plant's roots or stems, hung on the plant, or even lightly placed on it, as the tip of the negative electrode 4 discharges.
High-voltage negative charge forms a negative electric potential field at plant roots, driving positively charged particles through electroosmosis. The high-voltage negative charge reduces the potential on the outer surface of the cell membrane (e.g., from −70 mV to −50 mV), narrowing the transmembrane potential difference, enhancing proton pump activity, and acidifying the cell wall (pH decreases by 0.4-0.6), promoting cell elongation (e.g., cucumber stem elongation rate increases by 22%). K+ efflux channels are close, Ca2+ influx channels are open, and intracellular Ca2+ concentration rises (triggering downstream signaling).
High-voltage negative charge (e.g., −5 kV pulses) stimulates root NADPH oxidase (RbohD) to produce superoxide anions, with (O2 −), H2O2 concentration rising to 1.5 times within 30 minutes, activating the MAPK signaling pathway and inducing a 3-fold upregulation of auxin (IAA) synthesis gene (YUCCA6) expression (Arabidopsis experiment).
The cathode electric field promotes the polar distribution of PIN2 protein (auxin efflux carrier) in root tip cells, increasing auxin transport rate to the root tip by 40%. The negative electric field stimulates IPT3 gene expression in root tip cells, elevating cytokinin (ZR) content in maize roots by 25% and increasing lateral root count by 35%.
In the cathode zone, pH increases (due to H+ being consumed to generate H2), promoting the proliferation of alkaliphilic microorganisms (e.g., nitrogen-fixing bacteria Azospirillum), increasing soybean root nodules by 50%. A negative electric field (−3 kV/m) can eliminate 80% of Fusarium in the rhizosphere, reducing soil-borne disease risks.
After high-voltage negative charge treatment on leaves, the stability of PSII reaction center D1 protein improves, with light energy conversion efficiency (ΦPSII) increasing by 12%. The negative electric field reduces K+ efflux in guard cells, expanding stomatal aperture by 15% and increasing CO2 absorption rate by 20%.
Understandably, high-voltage negative charge promotes plant growth through a multi-cascade reaction of ion accumulation-membrane polarization-ROS signaling-hormone regulation, essentially utilizing electric field polarity to directionally regulate plant physiological processes.
In other embodiments (not shown), the negative voltage generator 3 adopts a full-bridge LLC resonant topology, with the resonant capacitor using an 0805 package MLCC made of a C0G material, and the inductance value set to 68 μH. When the power supply 2 inputs 12 V DC, a continuously adjustable output of −1 kV to −5 kV is obtained through frequency modulation (80-150 kHz). The biomimetic micropillar array (4a) of the negative electrode 4 is fabricated using PDMS replica molding technology, with a pillar height of 500 μm, a diameter of 100 μm, and a spacing in a gradient distribution (150-300 μm), creating a 0.5-3 kV/cm gradient field in the contact interface.
The negative voltage device 1 also includes a housing 10. The negative voltage generator 3 is installed inside the housing 10, and the power supply assembly further includes a solar panel 8. The solar panel 8 is mounted on the housing 10 and electrically connected to the power supply 2. The solar panel 8 is typically used outdoors, placed in sunny locations to supply power to the power supply 2.
A protective plate 9, which fits against the solar panel 8, is slidably installed inside the housing 10. When the solar panel 8 is not in use, inserting the protective plate 9 into the housing 10 forms a protective enclosure for the solar panel 8 with the housing 10 and the protective plate 9.
In specific implementations, a solar charge controller, an energy storage battery bank, and an inverter are arranged between the solar panel 8 and the power supply 2. The solar charge controller, energy storage battery bank, and inverter are all installed inside the housing 10, with electrical connections between the solar panel 8, solar charge controller, energy storage battery bank, inverter, and power supply 2.
The solar charge controller serves as the first-stage regulation device in the photovoltaic system, optimizing the output power of the solar panel 8 and protecting the energy storage equipment. The MPPT controller adjusts the unstable DC output of the solar panel 8 to a voltage range suitable for the battery by tracking the maximum power point (MaxPowerPointTracking) in real-time, while preventing reverse current flow from the battery at night. The PWM controller achieves similar functionality through pulse-width modulation but with slightly lower efficiency than MPPT.
The energy storage battery bank acts as an energy buffer unit, storing surplus electricity and releasing it during insufficient sunlight. Lead-acid or lithium-ion batteries should be selected based on application scenarios—for example, deep-sea equipment requires corrosion-resistant energy storage batteries. The battery bank capacity must match load requirements and solar fluctuation cycles.
If the load requires AC power, an inverter is needed to convert the DC power from the battery into stable AC power (such as 220 V/50 Hz), which is then supplied to power supply 2 through a voltage stabilizing circuit for stable charging. For DC loads, a DC-DC conversion module is required to boost or buck the battery voltage to the value required by the load, supporting a wide input range (2.8-40V) and high-power output (200 W), with intelligent protection mechanisms (overcurrent, overvoltage, overtemperature) ensuring system safety.
In other embodiments (not shown), the power supply assembly is an external power source connected to power supply 2 to provide power, typically used indoors, where the external power source is mains power.
In other embodiments (not shown), the power supply assembly is a rechargeable battery used to power power supply 2, generally for indoor use.
The exterior of housing 10 is provided with a USB charging interface 21, allowing power supply 2 to be charged using a 5V mobile phone charger.
In other embodiments (not shown), the power supply 2 is a wireless power supply module, including a receiving coil (2c) and a resonant capacitor (2d), operating at a frequency of 6.78 MHz with a transmission efficiency of 75%. The negative electrode 4 is made of a conductive hydrogel material with a volume resistivity of 1-10 Ω·cm and a water content of ≥80%.
In other embodiments (not shown), power supply 2 uses a high-capacity lithium-ion battery charged via a USB port, suitable for environments without light.
The negative electrode 4 is electrically connected to the negative voltage generator 3 via a wire 5, making the installation and connection of the negative electrode 4 more convenient.
The exterior of housing 10 is equipped with a switch 6 electrically connected to the negative voltage generator 3, facilitating the control of activation and deactivation of the negative voltage generator 3.
The interior of housing 10 houses a control circuit board 7 electrically connected to the negative voltage generator 3. Through the control circuit board 7, the negative voltage generator 3 can be adjusted to deliver varying voltages, currents, and frequencies based on different plants—high negative voltage (−6000V to −5000V) with microcurrent for large plants use, while lower negative voltage (−2000V to −100V) with microcurrent for small plants.
In other embodiments (not shown), the negative voltage generator 3 is equipped with a rotary knob adjuster, allowing users to manually select preset voltage levels (e.g., “large trees” or “herbaceous plants” modes), with the control circuit board 7 automatically matching the corresponding current and frequency parameters.
In other embodiments (not shown), the control circuit board 7 includes a voltage monitoring function that alerts the user via an indicator light when the power level falls below a threshold.
The negative electrode 4 is equipped with a mounting hole for easy attachment to plants.
In other embodiments (not shown), the negative electrode 4 adopts a magnetic adsorption or clamping structure to accommodate different plant morphologies.
From the above description, it can be seen that the aforementioned embodiments of the present disclosure achieve the following technical effects: by configuring the negative voltage generator 3 to produce negative high-voltage microcurrent and connecting it to plants via the negative electrode 4, since the primary energy source for plant growth is photosynthesis and light irradiation promotes molecular movement, the connection of the negative electrode 4 to plants increases internal electrons and facilitates greater electron migration, thereby promoting plant growth; this also has a pest-reducing effect; additionally, the negative charge helps enhance the absorption of potassium, nitrogen, phosphorus, and other substances by plants, further stimulating their growth; moreover, the negative electrode 4 can be attached to plants without burning their roots, offering simplicity, safety, and a positive user experience.
In the description of the present disclosure, it should be appreciated that directional terms such as “front, rear, up, down, left, right”, “horizontal, vertical, perpendicular, horizontal” and “top, bottom” etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description. In the absence of a contrary explanation, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present disclosure; the directional terms “inside, outside” refer to the inside and outside relative to the contour of each component itself.
For the convenience of description, spatial relative terms such as “on . . . ”, “above . . . ”, “on the upper surface of . . . ”, “upper” etc. may be used here to describe the spatial positional relationship of a device or feature with other devices or features as shown in the drawings. It should be appreciated that spatial relative terms are intended to encompass different orientations of the device in use or operation other than the orientation described in the drawings. For example, if the device in the drawing is inverted, the device described as “above other devices or structures” or “on other devices or structures” will subsequently be positioned as “below other devices or structures” or “under other devices or structures”. Thus, the exemplary term “above” can include both “above” and “below” orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here should be interpreted accordingly.
In addition, it should be noted that the use of terms such as “first”, “second” etc. to define components is for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning, and therefore should not be understood as limiting the scope of protection of the present disclosure.
The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure can have various modifications and changes. Any modifications, equivalent replacements, improvements etc. made within the spirit and principles of the present disclosure should be included within the scope of protection of the present disclosure.
